asked • 02/17/21One-third of an orchestra's musicians play violin or viola and another one-quarter play cello or contrabass. What fraction of the orchestra's musicians play either violin, viola, cello, or contrabass?

Fraction that play violin or viola = 1/3
Fraction that play cello or contrabass = 1/4
Total = 1/3 + 1/4
The common denominator is 12, so:
Total = 4/12 + 3/12 = _____?
